Buddleia 'Grand Cascade'
Grand Cascade Butterfly Bush
Description
Think all Buddleia look the same? Think again! Unlike the typical Butterfly Bush, the panicles on this flowering shrub cascade downward, similar to the look of weeping willow or a bridalwreath spirea. Light lavender purple flower panicles are enormous at 12-14" long and 4" thick. They're nearly the size of your head! Compared to 'Lavender Cascade', this Buddleia is a slightly bigger in overall size, but it's the flower panicles that are significantly larger. Butterfly Bushes have certainly earned their place in the garden over the years, and its easy to see why. Just when we need a breath of fresh air in the late summer heat, they happily burst into bloom. At a time when many other plants are already spent, buddleias are just beginning their show. Their passive coloring and texture makes a wonderful backdrop for perennials, and you'll love the butterflies, bees, and hummingbirds that flock to their honey-scented blossoms. Buddleias should be planted in a full sun location with fertile, moist, well-drained soil. Studies have shown that adding lime to the soil will result in increased growth and better floral quality. They are also moderately drought tolerant once established. Since they frequently die all the way back to the ground in northern winters, it is best to cut back all of the old wood to about 12" in the spring. Doing so will result in more compact plants. They will quickly grow back to their normal height by fall and will flower just as prolifically in late summer since they bloom on new wood. You may notice that the flowers tend to be longer and deeper colored in cooler weather. Buddleias tend to break dormancy late in the spring, so don't worry if you don't see anything happening with them when your other shrubs start to leaf-out. These are very durable and reliable plants. 'Grand Cascade' quickly reaches 6' tall and spreads 8'.
